Answer:
30%
Step-by-step explanation:
A percent can be found by dividing the part by the whole, or
part/whole
In this case, the part is the amount he spent on fruit. The whole is the total amount he spent.
amount spent on fruit/ total amount spent
He spent $18 on fruit, and $60 in total.
$18/ $60
Divide 18 by 60
18/60
0.3
Convert 0.3 to a decimal by multiplying by 100 or moving the deicaml place two spots to the right.
0.3*100=30
0.3--> 3.0 --> 30
30%
He spent 30% on fruit.
Answer:52
Step-by-step explanation:
Any score between 76 and 84 will be 1 deviation from the mean.
To figure this out you subtract 4 from 80 (80-4 = 76) and you add 4 to 80 (80+4) = 84 and that tells you that most of the scores will fall between 76 and 84 which is 1 deviation from the mean.
Answer:
y = 3.2 units
Step-by-step explanation:
Find the missing angle measure x. Use the fact that all interior angle measures in a triangle add up to 180 degrees.
- 55 + 50 + x = 180
- 105 + x = 180
- x = 75
We can use the Law of Cosines to determine the missing side length y.
- a² = b² + c² - 2bc · cos(A)
Let's set UW (y) as a, WV as b, and UV as c. Therefore, ∠V must be A, ∠U must be B, and ∠W must be C.
Use the Law of Cosines to solve for a (side length y).
- a² = b² + c² - 2bc · cos(A)
- a² = (4)² + (3.5)² - 2(4)(3.5) · cos(50)
- a² = 28.25 - 28cos(50)
- a² = 28.25 - 17.99805307
- a² = 10.25194693
- a = 3.20186616366
Side length y is equal to 3.2 units.
Answer:
Where: 28 is the old value in 36 is the new value in this case we have a positive change increase of 28.571142857
